New heater. Slow drip

[Charlied24]

Installed new mastertemp 400 and all went well. I noted a small water leak inside heater (not at union which is dry) Is this the gasket on the manifold? It leaks very slow from just above the puddle. Dry all around except there. Should I take this apart ? Try to submit Warranty (I here they will likely deny a diy) thanks in advance.

Did you register the heater when installed? Did any pool professional "verify" the install and provide an invoice? If so you may be able to warranty , you would just need to upload that invoice. If not, i would try loosening the zink bolts that hold the manifold then re-tourqing in the correct sequence to 75-115 in lb.
You may want to fully remove the manifold and lube the big o-ring and make sure it is seated properly.

May just need to snug that lower-left bolt (or all of them), but just a little.
